Exactly, then have a ton of great exclusives and above all, Gears of War 2. Nuf said, as the wise men say.
And Wii have Super Mario Galaxy and probably an upcoming Zelda.
Now, I have not played MGS4 and probably should not speculate too much, but personally I've never regarded the MGS-series as that great. The first was a small revolution, although more of a movie than actual game, but then it went with the second and third downhill.
I haven't been playing that much recently. I am disappointed with GTA IV. It is exactly like playing San Andreas with a few improvements here and there. It's an amazingly well crafted game, but it does not entertain me to the same extent anymore. When I think about games like the above mentioned Gears of War, Portal and Super Mario Galaxy, these are games that was a joy ride from beginning to the end, but GTA IV just isn't. There are some great parts, but between them there's too much time consuming driving, hanging out with pals, repeating missions, using a pretty badly implemented shooting-system and other stuff.
